To all whom it may concern: 7

7 Be it known that I, LEVI M. BOWMAN, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Hydrocarbon-Burn. ers; and I do hereby declare the following tov be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in fuel burners, and has particular reference to a hydrocarbon burner.

An object of the invention is to improve the construction of hydrocarbon burners by providing novel means whereby the noise, usually resulting from the combustion of gases in burners of this character, is e1iminated, and the efficiency of the burner en hanced by increasing its heating capabilities.

Another. object is the provision of a burner wherein the action of breaking up the fuel into a gas to be mixed with air to form a combustible mixture is facilitated, and the production of a blue, transparent, odorless and smokeless flame insured.

A further} object is to provide a burner of this character embodying strength, durability,simplicity of construction and cheapness of manufacture. Y

The inventive idea involved is capable of receiving a variety of mechanical expres sions, some of which, for the purpose of illustratingthe invention, are shown in the accompanying drawings, wherein Figure 1 is a side elevation of the burner constructed in accordance with the invention Fig. 2 is an enlarged vertical longitudinal section therethrough,

Fig. 3 is a fragmentary top plan view,,

partly broken away, and shown in section,

Fig. 1 is a section on the line'4lof Fig.

Fig. 5 is a detail side elevation of a slightly difl'erent form of burner cap from that shown in Fig. 1, and

Fig. 6 is a horizontal section through the burner cap shown in Fig. 5.

The accompanying drawings illustrate what are now believed to be the preferred forms of the invention, and by particular reference to Figs. 1 to 4 inclusive it is to be seen that the invention comprises an outer substantially cylindrical casing 10, open at its top and bottom, and constructed of any desired material to form an outer wall for the burner. Disposed centrally within the upper portion of the casing 10 is an air tube 11, having an enlargement 12 atits upper end, provided with a horizontal annular supporting flange 13, upon which is mounted the burner cap 15, forming a gas chamber and provided in the vertical wall thereof with a plurality of spaced vertical flamedistributing openings 16. The air tubell is supported Within the casing by means of an arm or enlargement 17 formed integrally with the air tube, intermediate the ends.

thereof, and projecting laterally therefrom with the outer end of the arm extending through the adjacent upper portion ofothe casing 10. p

Preferably surrounding the lower portion of the burner cap 15 is the horizontal coil portion 18 of a fuel cracking orbreaking up evice, one end of which-terminates in an inlet 19, while the other end thereof is bent at right. angles to form a depending pipe section 20, which extends through the arm 17 as best illustrated in Fig. 2, the lower end of said pipe 20 being screw threadedto receive a second pipe21, arrangedhorizontally and extended inwardly to, terminate beneath the lower end of the air. tube, the upper surface of said pipe 21 .being provided in that portion below said air tube with the jet opening 22, through which the gas from the pipe 21 passes upwardly into the tube 11, where the same mixes with the air drawn into said tube through the bottom of the casing 10. In order to control the flow of gas through the opening 22 and consequently the size of the flame produced in the burner cap 15, there is provided a needle valve 23,

I slidably mounted in a boss 24 formed upon the lower portion of the pipe 21, and having a packing nut 25 threaded thereon to pre vent leakage of the gas from the pipe. The

lower end of the needle valve is pivotally connected to an adjusting lever 26 employed. to regulatethe valve to control the flow of gas, and said lever 26 is pivoted intermediate its ends at 27 to the lower end of a supporting arm 28, the upper end of which is secured to the outer end of the arm 17.

Formed upon the outer end of the inlet 19 there is provided an enlarged fuel check chamber 29, one end of which is screw threaded, as at 30, for connection with the fuel supply pipe 30. A quantity of gravel, asbestos, or the like, is placed in the chamber 29, and held in position therein by means of a wire gauze 81, and it will be obvious that by reason of having to pass through this material the fuel will be properly fed into the cracking device or chamber formed by the coil 18 and pipe 20, so that what is commonly known as breathing and puffing at the burner cap will be prevented.

In practice, in order to start the burner it is necessary that the cracking chamber and particularly the portion 18 thereof become heated and this may be preferably done by placing a small quantity of alcohol, or other inflammable liquid, in a tray beneath the casing 10, and igniting said liquid so that the heat therefrom will pass upwardly through the casing and impinge against the coil 18, and in this manner suflicient gas will be generated in a very short time. The burner fluid, such as kerosene, is fed through the chamber 29 from the feed pipe and from thence into the packing chamber where the fuel is broken up to form a gas, which passes downwardly through the pipe 20 into the pipe 21, and from thence through the jet opening 22 controlled by the needle valve :23. After passing through this opening 22 the gas passes upwardly and mixes with the air drawn into the air tube 11, and the combustible mixture then enters the gas chamber formed by the burner cap, where the same may be'ignited and the flame therefrom will pass through the distributing opening 16, and at the same time heat the coil 18 to facilitate the generation of the gas therein.

In Figs. 5 and 6, the burner cap shown therein is provided with a plurality of spaced horizontally disposed flame-distributing openings 16 instead of the vertical openings or slots described in connection with the other form of burner cap.

What is claimed is:

1. In a burner of the class described, the combination of a casing, an air tube disposed therein and having an annular supporting flange adjacent its upper end, a burner cap supported by said flange, an arm extending from said air tube and through said casing, a cracking chamber having a portion surrounding said burner cap and another portion depending below the same and extending through said arm of the:air tube, valve means disposed beneath saidair tube for controlling the flow of gas from the cracking chamber into the air tube, and means supported by said armof the air tube for adjusting said valve.

2. A burner of the class described comprising, a cylindrical casing,an air tube arranged within the casing, an annular supporting flange formed integral withsaidair tube and disposed adjacent its upper .end thereof, a burner cap carriedby said annular flange and having openingstherein, a tubular fuel supply member coiled about said burner cap and extending below said air tube, the lower portion of-said fuel supply member having a discharge opening therein, and a valve for controlling the discharge opening in said fuel supply member.

'In testimony whereof I aflix my signature in presence of two'witnesses.
